This set contains an insert for the King of Tokyo box that should be able to fit all of the currently available expansions (Power Up! + 4 monster packs) or just the base game.
The insert/divider is available in 2 types - a 245x245 mm version that takes up the entire box or a 220x220 mm version (that can be printed on an Ender 3 Pro) with additional 220x24 mm side pieces. Either way, all pieces can be super-glued or simply laid into place after printing to keep all of the components and cards nicely separated and easily retrievable.
This set also includes:
1) An organizer for the circular tokens that come with the base game, the Power Up! expansion, and the Cthulhu Monster Pack.
2) An energy cube dish with a screw-on lid. Both parts can be printed without support.
I'm aware that there are some other components (dice, cards, and punchouts that come with the other expansions. Those other components will certainly fit in this insert, but I did not make specific organizer pieces for them, since they are used infrequently and I wanted this organizer to potentially accomodate future expansions as well.
